	 * The Multitouch class manages and provides information about the current
	 * environment's support for handling contact from user input devices,
	 * including contact that has two or more touch points(such as a user's
	 * fingers on a touch screen). When a user interacts with a device such as a
	 * mobile phone or tablet with a touch screen, the user typically touches the
	 * screen with his or her fingers or a pointing device. While there is a broad
	 * range of pointing devices, such as a mouse or a stylus, many of these
	 * devices only have a single point of contact with an application. For
	 * pointing devices with a single point of contact, user interaction events
	 * can be handled as a mouse event, or using a basic set of touch events
	 * (called "touch point" events). However, for pointing devices that have
	 * several points of contact and perform complex movement, such as the human
	 * hand, Flash runtimes support an additional set of event handling API called
	 * gesture events. The API for handling user interaction with these gesture
	 * events includes the following classes:
	 *
	 * 
	 * 
	 *  * flash.events.TouchEvent
	 *  * flash.events.GestureEvent
	 *  * flash.events.GesturePhase
	 *  * flash.events.TransformGestureEvent
	 *  * flash.events.PressAndTapGestureEvent
	 * 
	 * 
	 *
	 * Use the listed classes to write code that handles touch events. Use the
	 * Multitouch class to determine the current environment's support for touch
	 * interaction, and to manage the support of touch interaction if the current
	 * environment supports touch input.
	 *
	 * You cannot create a Multitouch object directly from ActionScript code.
	 * If you call `new Multitouch()`, an exception is thrown.
	 *
	 * **Note:** The Multitouch feature is not supported for SWF files
	 * embedded in HTML running on Mac OS.
